I'd like to have these too. DirectFB needs to know if the chip is G400 or
G450/G550. Currently we just pick the first entry found in /proc/bus/pci
and hope it has the same chip type as the /dev/fb we're using.

Why does this have to be in the kernel? You already have the PCI IDs so
you should be able to handle this in user space.
